Some more background to the Battle of Pinjarra:

H W Bunbury was stationed at the Swan River Colony just after the Battle of Pinjarra. He spent many months exploring the south west and was widely accepted as being a friend of Aboriginal people and worked with them on several of his expeditions. Here's what he wrote in one of his letters home in 1836, two years after the ‘massacre’:

“When he {Thomas Peel) settled at Mandurup, an officer & Detachment were sent for his protection, as the natives shewed themselves very hostile; they murdered not only several of his men but also several soldiers, & actually blockaded two or three of the latter who were left in the Barracks until a stronger Detachment was sent from Head Quarters to their relief. The natives speared Peels horses & cattle & and kept the settlement in constant dread & alarm until the Pinjarrup affair taught them our strength.”

Blaming the White man is all the Aborigines have to cover their lack of progress due to not being as cohesive a society as most of the World's cultures were in that era of exploration.
If they had a real Welcome to Country none of the conflicts would have occurred in the first place. Aboriginal history has been made a huge lie by mostly white academics & now the indigenous have literally nothing believable so far as culture is concerned.
The Aboriginals have been isolated for too long & unfortunately that cost them dearly. However, to try to turn many wrongs into a realistic Right is failing everyone not just them.
I just hope that before long a true Aborigine will find a way to accept history & use the experience of the failures to bring about a better future & it can be done if the White & mixed race Academics can be prevented from further inventing Australian history !
